Whoa. The Sheriff behind Nancy Guthrie's case is at risk of being replaced! For nearly two months now, Savannah Guthrie's 84-year-old mother has been missing after she vanished from her home in Tucson, Arizona. Frustration had been building since the first week of the investigation amid continued complaints that the Sheriff has mishandled the case. His supposedly large ego has been called into question, and he's been accused of withholding information from the FBI.
